# Steam Workshop and Publishing your Mods

Learn how mod packaging and publishing works in the GEM RTS engine, including saving, uploading, and sharing your creations through the Steam Workshop, demonstrated using [Men of War II](https://bestway.com.ua/games/men-of-war-ii/) as an example.

Main stages of mod publishing:

* Package setup (0:12–0:25):\
  In the game settings, open the Packages section. If the publish button is inactive, this means that the package does not contain any mod files.
* Moving files (0:30–1:06):\
  New files created in the Editor are automatically saved in the editor local changes folder. These files must be manually moved into your custom package folder, such as tutorial, using Windows Explorer.

{% hint style="warning" %}
Do not move the **.info** file, as it is required for the package to function correctly inside the engine.
{% endhint %}

* Publishing (1:25–1:45):\
  After moving the files, the game must be restarted. Once restarted, the publish button becomes available and the mod can be uploaded to the Steam Workshop.
* Workshop visibility (1:47–1:53):\
  By default, newly uploaded mods are set to hidden status. This gives creators time to prepare descriptions and add screenshots before making the mod publicly available.

Although the workflow is demonstrated using Men of War II, the same publishing principles apply to other games built on the GEM RTS engine.
